The Exhaust Behind the Equipment.
Meet CS COSMOS STIHL at Equip Expo, Oct. 20 to 23, Louisville, Ky. | Booth #8010
Single-Source Exhaust Engineering for outdoor power equipment OEMs. Mufflers and exhaust systems engineered, built and delivered at production scale since 1972.
Since 1972 | 5M+ units a year | Manufactured in South Chicago Heights, Ill.
We make parts for STIHL, Echo, Stanley Black & Decker, Honda, Kawasaki, Walker and Husqvarna.
Built for the three teams that decide
​
Bring us in early. We engineer the exhaust around your engine and chassis.
​
One accountable supplier, from prototype to 5M+ units a year.
​
I need quality documentation
A documented quality system with in-house control of forming, welding and assembly.
Exhaust and metal-formed components for the equipment you build
Mufflers, complete exhaust systems, heat shields, brackets and stamped components, engineered, finished and assembled under one roof in South Chicago Heights, Ill.
Zero-turn and ride-on
Mufflers, exhaust systems and structural parts for commercial zero-turns and garden tractors.
Handheld outdoor power
Compact exhaust, brackets and guards for chainsaws, trimmers, blowers and brush cutters.
Battery-powered
Stamped housings, trays and enclosures for electrified mowers, handheld tools and utility platforms.
Stationary power
Exhaust for portable and standby generators, pumps and engine packages where sound and heat routing are critical.
From first drawing to full production
One team and one ISO 9001-aligned quality system from DFM review through production launch, with PPAP-level documentation and lot traceability.
1. DFM review
Bring us in early. We review materials, forming, welds and coatings for cost and producibility before tooling.
2. Prototype
Working prototypes fast, so you can check fit, sound and heat early. Single-source engineering supports fast project lead times.
3. Validation
Dimensional checks, leak testing, flow analysis and noise measurement before production launch.
4. Production
Seasonal capacity planning, lot traceability and packaging built for line-side delivery.
Schedule time with us at Equip Expo
Tell us what you are working on and when you will be at the show. We will set a time to meet at our booth, #8010, in Louisville or follow up after Equip Expo.
